In the following, you are provided with instructions for using the KEEPALIVE

support facility added to the TCP/IP components for AIX

5.3 AIX KEEPALIVE support

The no (network options) command can be used by the root user to configure

KEEPALIVE frequencies.

no -o tcp_keepidle=nnn

no -o tcp_keepintvl=nnn

when nnn is in half-seconds.

The command tcp_keepidle specifies the interval of inactivity causing the TCP to

generate a KEEPALIVE transmission for an application that requests them.

The default is 14400 (2 hours).

The command tcp_keepintvl specifies the interval between the nine retry

attempts if a KEEPALIVE transmission is not acknowledged.

The default is 150 (75 seconds).

The no commands must be run each time the AIX system is started. Adding the

no commands to /etc/rc.net is a convenient way of automating this step.

Adding e.g.

no -o tcp_keepidle=480

no -o tcp_keepintvl=80

to /etc/rc.net causes the TCP to send a KEEPALIVE transmission if a TCP

connection has been inactive for 4 minutes and the application requested

KEEPALIVE transmissions, as AIX now does. AIX recommends these TCP

configuration settings to customers who use TCP/IP attached printers and the

device.

To view current settings enter

no -a

When the installation and configuration procedures for the PSF/AIX have been

completed, you are ready for printing.
